Contrary to popular belief, the frequency of paying ½ payments biweekly doesnt accomplish much, the real advantage is paying the extra principal (13.05 payments, or more, each year) which reduces the term and the interest paid. If you are considering signing up for a biweekly program, pay close attention to the cost. Some services have large setup fees and transaction fees. Also consider the credibility of any company handling your money, some have diverted payments into their own pockets, leaving borrowers to make payments twice (once to a corrupt service and a second time directly to the lender).
